Development of wave absorbing coating optimization software

Design and optimization of wave absorbing coating are of great interest in engineer- ing practice to decrease the scattering intensity of typical targets, such as missiles and aircrafts. Aimed to automatically select particular materials from the material database and design the thickness of each layer to form the optimized multi-layer wave absorbing coating, a universal software based on the genetic algorithm is developed using C++. Many important features and functions, such as optimization in multiple bands with multiple incident angles and different incident wave polarizations, partial assignment and partial optimization of wave absorbing layer parameters, build-in radar absorbing material database management, reflection coe±cients cal- culation and display of arbitrary wave absorbing coating are achieved in the developed software. The software development flow chart and basic modules are discussed. The functions and cor- responding friendly user interface are given. Su±cient numerical examples are shown at last, which demonstrate reasonable optimization results, high efficiency and stability of the developed software.
